Hello frnds , i need your help .. If i download any google app ( only 6 mb )my mobile is showing insufficient storage . but if I see the storage i have 394 mb free in Phone & 4 gb free in my memory card ... pls help me

im planning to buy this phone.., plz do let me know its advantages and disadvantages so that i can decide to go ahead wit my decisions or if there is any good phone with the same features and almost same price also..,

Xiaomi Redmi Note 4G is patetic. And I think its cause of MIUI cause I've heard CM Roms working smooth in this phone.
I had MIUI6 now on MIUI7. Both pathetic.
Poor RAM management. Camera heats and crashes. Also camera apps eat all resource and rapee all other apps. Almost all apps like whatsapp, snapchat etc lag. And OS also lags. Android on Nexus is way smoother. So its MIUI. 4G works excellent though. Battery life is good. Display is fine. Rest all is pathetic. Worst performance ever. Frequent reboots required. My device doesn't face heating problem as much as I've read about others, but once it heats and then the phone is fuc*ed. Dont buy this. There are many better options. And if possible pay a little extra for a peaceful experience for good.
